An insufficient capacitance will reflect ripples on the DC link that can provide unwanted harmonics which result
in more faults. Capacitors can absorb the regenerated power. By using sufficient capacity, the power
consumption will be reduced. In addition to coping with ripples on the DC bus, the capacitor can also absorb
part of the regenerated energy resulting from deceleration (see Regenerative energy). But using capacitors will
not be enough for large amounts of energy - the excessive energy needs to be dissipated with braking
resistors.
